I agree with Javier, keep the elbows down and out and ready to punch it behind your head. It's about where your elbows are already so not much change is needed.
The biggest issue I see is the movement of the jerk itself. 1) Don't rush into the dip. Make the dip a nice, smooth and controlled movement and then you can accelerate up. 2) You're leaning forward through the bar and your weight is WAY too heavy on the front leg. Distribute your weight about 50/50 between the front and the back foot. A great exercise for you would be Split Push Presses
. Notice in the video how Steve keeps his back knee soft and uses it as kind of a shock absorber to let his hips drop straight down to stabilize the weight without letting his weight shift.
